PATENT ,OFFIGE.

Patented; J an. 8 1907 Be it known that I, GHARLES E. MILLEIt, &

f citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Machines for Wrapping Tires', of which the following is a speci- This invention relates to new and useful improvements inmachines for wrapping tires, and it particularly pertains to a machine adapted for heavy Work, such as automobiletires. i

In the art as is ordinarily practiced when a tire is first made oris repaired it is neces-' ear to wrap strips, of fabric about three inc es wide tightly around the tire in order to hold the new rubber in lace when it is being vulcanized, It is a desideratum that the tire should be wrap ed very tightly, since the extreme pressure orces the new rubber into the cloth and causes it to adhere better than when the tire is Wrapped loosely. To attain a tight wrapping for the purpose above de-.-

scribed, it has been necessary heretofore to wrap the tire by hand, thereby increasing the expense of manufacture throu h a laborious and tedious operation, which'o tentimes fails of satisfactory results. v

It is thereforea primary object of the present invention to. provide a machine which shall automatically accomplish a tight wrapiiig, such as been heretofore done by and.

It is a provide means for adjusting the tension of the fabric as it is wound upon the tire.

The invention also aims to rovide means for feeding the tire in a circu ar ath about its center v and to provide. fee g means ada ted for tires of varying sizes.

The invention finally aimsto provide a device hich shall be simple in construction, inegpensive tomanufacture, andpractical and e cient in use.

The detailed construction will appear the course of thefol'lowing description,1n

' 'whichreference is had to the acconi anying drawings, forming a part of this spec' cation,

like characters designating like parts throughout the several views, whereine a Figure 1 is a plan view of a tire-wrappln apparatus constructed in accordance wit 1 ,m invention, and Fig. 2 is a side elevation a5 l l thereof.

In the practical embodiment of my invenfurther object of the inventionto tion Iemploy a supporting-frame 1, provided is intro ucedh A rotating with rearwardly-extending brackets or shoes I frame 1 and preferably comprises two L-bars open space ,7 shall register with the open s ace54. After the tire has been introduced t on h' the spaces 7 and 4 in their registerin re ation the space 7 is closed-by an arcuate lin 8, pivoted, as at 9, to one end of the fastening'device 10, as is shown in 2. t The tire-mapping means is carried y the the fabric (indicated by dotted lines in Fig.

2) is wound. The spool,11 is rotatably supported between arms 12, pivoted at 13 to t e central ortion of theframe 5. A stationary brake-b ock 14 is mounted uponsaid frame adjacent said spool and is designed to prevent the same'from unwinding too freely.

The brake-block 14 may either bear upon the.

frame 5 andcornprises a spool 1 1,.upon'vvhich frame. 5 and held in position by a suitable p s 001 itself; or upon the fabric, 'as-itis" die I sired. The arms 12 are normally drawn toward. the block 14 by retractilelcoil-s rings 115,.seoured to the frame 5, a's'at 16, an having their free ends threaded through the arms 12 and provided with'an'adjusting-nut 17. The nut 17 affords a means for tensioning the springs 15 and regulating the degree of pressure or tightnessof the fabric u on the tire during the winding operation. is rotated by means of frictional gears 18, journaled in ofl'set bearings 19, provided u on theframe 1. The gears 18 are mounte upon a shaft 20,. which carries a powerpulley .21. provided for centering the frame 5 with relation to the frame'l, and an'advantageous embodiment is shown in Figs. 1 and 2 comprising pe 'pheral flanges 22, carried bgthe ears 518; and overlying the sides 0 the ame l the frame -1 an comprises a supportln'ghe frame 5 The :tire-feedin means is mounted upon It is preferred that means be bracket 23, provided on, each side thereof 1 I provide collars 25, arranged on'each side of the frames with an ular-ext'ending depending arms 24, d at their lower ends with spaced land 5,; A shaft 26, provided with an op.- erating-handle 27, is journaled in the bracket 23 longitudinally of-the frame 1, the shaft 26 bein detachably held inposition by a screw breaded'Lthrou h sald bracket and engaging in ah annuiar groove 29, pgovided upon said shaft; The shaft 26 is t eaded,

. as at m l-and 31, inopposite directions on throu each side of the bracket 23, thethreads 30 and 31 passing through openings provided for said: shaft m pulley-supports 32 and 33. The supports 32 andi33 are formed with dependin converging arms 34, which pass the respective collars and are held t erein .by set-screws 35, which serve as a pivot. One of the arms 34, which, as shown, is upon thesupport 33, is hollow for the reception therethrough of a universal o erating-shaft'3-6, which at its end carries 't emain'feed-roller 37. Idle feed-rollers-38 are provided upon the ends of the remaining arms 34.. The rollers 38 are concaved, so as to conform to the curvature of the side of the tire A, the said tire being held'between said arms in pairs, a's'is clearly illustratedx In order to accommodate tires of different sides, the shaft 26 is rotated in the proper direction to simultaneously separate 'or bring together the-lower ends of the arms 34, which can thefeed-rollers.

T'e operation will-be readily apparent the fa ric automatically unwinding itself from said spool u on the tire as the'latter 1s fedproportlonate y by the means described.

While the elements herein shown and described are well adapted to serve the functionsset forth, it is obvious that various minor changes may be made in the proportions, sha' e, and arrangement of the several parts wit out departing from the spirit and scope of the invention as defined in the appended claims. l

' Having fully described my invention, what I claim is--' A machine of the type set forth comprising an annular sup orting-frame, an annular frame rotatably mclosed therein,sup-

orting arms carried by said last named a'me and pivoted thereto and a spool mounted between said arms.

2. A. machine of the type set forth comprising'an annular su porting-frame, an annular frame rotatab y inclosed therein, a

spool yieldably mounted u on said second 1 frame and a brake-block Baring against said s 00].

3. machine of the type set forth coin" prising in combination wit means for windmg fabric about a tire, of tire-supporting; means comprising a stationary support, '0 posed pulleys sus ended'therefrom-on pending pivoted s afts and means for ad-* gustably moving said shafts in either diIBC-l tion u on their res ective pivots.

- 4. machine oi tatably mounted t erein', means carried by ;said supporting-annulus for suspending a tire, means earned by said last-named annulus forwrapping a tire, and means on said supportmg-annu us for rotating said last named annulus.

In testimony whereof I afiix my signature in presence of two witnesses.
